How to find list of keys in laravel 8 cache files?

Question

Laravel

Laravel 8
File cache

For example, I save data with keys
user_1
user_2
user_3, etc. to the cache.

There are a lot of users in the database

And I need to clear the entire cache for user_*

How can I do this?

Answer 1

This is not possible with the file driver. The list of keys is not stored anywhere. Switch to drivers that support tagging.

Answer 2

Use cache tags, then you can just clear the tag.
